If an acronym is being utilized with swift and the word spoken for the acronym is not the appropriate word that is wanted there is a solution to get around this by utilizing the lexicon file. The lexicon.txt file can be created and modified in every voice directory to manipulate how certain words are being pronounced. So if the acronym is pronouncing the wrong word just simply make a lexicon entry for the acronym with the appropriate phonemes to the word that is wanted. For more information about the lexicon file along with a list of phoneme definitions please select the following link to the Cepstral F.A.Q. page: http://cepstral.com/cgi-bin/support?page=lexicon
